Hall and Clauschee had recently split up, and in August, Clauschee had taken out orders of protection against Hall, Busse said. The order was dismissed Aug. 20.

Busse said they confirmed Hall was driving a red 2002 PT Cruiser with Arizona license AVJ5881. The car has been listed in national databases as a felony vehicle in relation to the shooting.

Officers told CBS 5 News that just after 8 a.m. Monday, neighbors in the 2600 block of South 110th Drive reported hearing several gunshots. When officers arrived, they found the garage door open and the 28-year-old Clauschee dead on the floor from multiple gunshots.

According to officers, the 4-year-old girl was still restrained in the child's seat and was unharmed. Investigators said they believe Clauschee had just buckled her daughter in the car seat when the gunman approached.
